China was outraged by Japanese Prime Minister Yoshihiko Noda’s remarks to reporters at the UN General Assembly, and has urged Japan to cease immediately all actions that infringe China’s territorial integrity and sovereignty.

“China is strongly disappointed and sternly opposes the Japanese leader’s obstinacy regarding his wrong position on the Diaoyu Islands issue,” Chinese Foreign Ministry spokesman Qin Gang said in a written statement on Thursday.

Qin’s remarks came following Noda’s insistence when responding to reporter’s questions at the UN General Assembly on Wednesday that the Diaoyu Islands “are an integral part” of Japan’s territory in light of history and of international law.

“China has sufficient historical evidence and legal basis to prove the Diaoyu Islands have been an inseparable part of Chinese territory since ancient times,” Qin said, citing the fact that the Qing court was defeated in the Sino-Japanese War in 1895 and forced to sign the unequal Treaty of Shimonoseki and cede to Japan “the island of Formosa (Taiwan),” together with all islands appertaining or belonging to the said island of Formosa including the Diaoyu Islands.
